GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(550, 106) = 29150
GCD(550, 106) = ( 550 x 106 ) / 29150
= 550 / 106
= 550
Step2:
LCM(2, 688) = 688
GCD(2, 688) = ( 2 x 688 ) / 688
= 2 / 688
= 2
Step3:
LCM(2, 258) = 258
GCD(2, 258) = ( 2 x 258 ) / 258
= 2 / 258
= 2
So, Greatest Common Divisor of 550, 106, 688, 258 is 2
